Variety description

10 August 2026

The variety belongs to the Westerwold ryegrass group and is characterized by an intermediate growth type with an erect habit. The plants possess the ability for active growth and high forage mass productivity in the autumn-winter period, outperforming standard varieties during the autumn, winter, and spring seasons.

The plants have an excellent sanitary profile, including high resistance to rust and tolerance to rice blast. The variety has good palatability for livestock. To achieve maximum yield, early autumn sowing is recommended with a seeding rate of 20–25 kg/ha at a depth of 0.5–1 cm, followed by intensive nitrogen fertilization.
